The Green Party finance spokesperson has today called for the immediate resignation of the Irish Nationwide chief executive.
It comes after it emerged last week that Michael Fingleton received a bonus of €1m just weeks after the Government introduced the €440bn guarantee to protect the banking system.
Dan Boyle said Mr Fingleton's conduct to date has been a disgrace and the failure to hand back bonus payments shows contempt for all Irish citizens.
"Michael Fingleton has run the Irish Nationwide Building Society like his own personal fiefdom," said Boyle.
"His conduct shows little care for savers and homeowners who have placed considerable faith - and in some cases placed their life's chances and the fortunes of their families - in that institution.
"A week has gone by since we learned that Mr Fingleton was the only bank boss to receive a pay rise last year - bringing his salary to €1m in spite of Irish taxpayers now being exposed to the tune of hundreds of billions to underwite reckless banks.
"Since then we have heard nothing - Fingleton of all people must now go!"
